T o ZZ whom. 'it m (1y concern.

Be it known that we, Jantes D. ReirsNYnnn and HENRY G. Scnwnno'rnn, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful improvements in lvlachines for Forming Sealed Wrapped Packages, ot which the following is a specification.

rlihis invention relates generally to box or package wrapping or covering machines and more particularly to a machine for producing what will be termed a sealed wrapped package,7 that is to say, a package wherein its covering wrapper is formed from a single adhesively coated blank having a body portion and integral side, end and top covering wings or iiaps, all adherently atlixed to all of the exterior wallsot the box 'which forms a part of the package, the object being to provide a completely covered and sealed wrapped package.

Boxes wrapped and sealed in the manner described and as herein illustrated are especially adapted for use in connection with those classes of merchandise which are affected by atmospheric changes and conditions, or are subject to attack by certain species ot vermin, and the packages made in. a machine embodying the present invention are peculiarly adapted for use in connection with the manufacture and sale ot various kinds of breakfast foods, baked products, such as crackers, biscuits, and the like, and various other classes ot merchandise that are either subject to deterioration through changes in the atmosphere or attacks by vermin.

Another object of the invention is to provide a machine for adherently applying a single blank to allotl the exterior walls of a box and wherein those portions oi' the blank that cover the various walls of the box are provided with printed matter constituting labels for the several walls ot' the box when the blank is applied thereto, the purpose being to so apply the blank to the walls of the box that when the box is opened "for removal of its contents, the wrapper with its labels will not be destroyed as is the case with a wrapper that is loosely applied to a box and which must be removed when the box isopened for removal ot' its contents.

The invention hasI for its purpose various other more or less important objects, all of which will appeartrom a reading of the following specification ltaken in connection -with the accomj'ianying drawings wherein we have illustrated and described one embodiment of the invention and one form ot' sealed wrapped package, it being understood that the present showing is only by way of illustration as we believe ourselves 4n'iachine taken in a plane substantially at right angles to the plane of Fig. l. Fig. 3 is a plan indicating the preferred form of wrapper blank upon which the machine operates to cover the box. Fig. et. is a perspective illustrating a box or container such as may be covered with this wrapper blank by this machine. Fig. is a diagrammatic view illustrating the mode of operation of the machine in applying the wrapper to the package. Fig. (3 is a (fliagrammatic plan indicating tht` next operation ot' the machine in applying the' wrapper to the box. Fig. 7 is a. side elevation further illustrating the operation indicated in Fig. G. Fig. 8 is a side elevation diagramn'iatically .indicating the. next operation iu applying the wrapper. Fig. 9 is a diagrammatic plan and partial section particularly illustrating the means for applying the projecting portions of the wrapper to the remaining uncovered side or wall of the box. Fig. '10 is a view similar to Fig. t), but particularly illustrating the manner in which these instrumentalities cooperate'. Fig. 11 is a vertical section further illustrating the operation of folding parts of the wrapper upon the uncovered side. Fig. l2 is a view indicatingthe next and last operation which eifccts the application of the long flap of the wrapper to the uncovered side or wall ot' the package. Fig.

13 is a fragmentary view showing diagram' matically and partially in section the mechanism for moving the package laterally to effect the application of the long Hap of the wrapper to the package. Fig. 14 is a perspective illustrating a completely covered package and particularly illustrating the manner in which the completely applied wrapper covers the box.

Before proceeding to a detailed description of the machine and its operation, it should be understood that fundamentally the function of the machine is to adhesively ap# ply the wrapper to all the walls of a box, except one, in such a way that there is a remaining area of the wrapper which is then applied to the remaining uncovered wall or portion of the side of the box. The sealed wrapped package produced by this machine, is substantially air-tight, and this assists materially in preserving in a fresh state the contents of the package. Such packages are particularly desirable for candy, cereals, etc., crackers and biscuits.

The wrapper which is applied by the machine can be readily printed upon before its application and this obviates the necessity of applying any labels to the package after being delivered by the machine. This greatly reduces the cost of the package. Furthermore, as t-he wrapper is adherent to the wall of the package at all points, it will not come loose from the package when the package is open, which insures that the printing matter on the package remains lntact. l'

In Patent No. 1,131,792, issued March 1G, 1915, one ofv the present co-applicants was a co-patentee. In that patent there was disclosed a machine which operated to cover all sides of a box except one with the wrapper and this remaining uncovered side was afterward covered by a label. The application of this label entailed another operation and materially increased the cost of producing the complete, sealed, wrapped package. The present invention operates upon an unwrapped box and applies a single wrapper blank to all of the walls of the box completely covering the box vanddelivers the .box ready for shipment and sale. Producing the completely wrapped box through the operation of one machine avoids rehandling the partly Wrapped package and very greatly increases the economy of operation andthe amount of output or capacity of the machine. It also produces a neater package.

Referring more particularly to the parts, represents the frame of the machine which may comprise a base 21, a lower table 22 and an upper table The upper table 23 preferably is arranged to carry folding instrumentalities 24: for effecting the application of the wrapper to the package. `In order to clearly understand this operation,

reference should be. had to Fig. 3 which illustrates the preferred form of wrapper blank which is to be applied to a package 25 such as illustrated in Fig. 4.

The wrapper blank 26 preferably comprises a4 body portion 27 of substantially rectangular form having integral side wings 28 and 29 and integral end wings 30. The side wings 28 and 29 have at their ends, end portions or corner laps 31 for a purpose which will appear hereinafter. The wings 28 and 30 have marginal extensions 32 preferably as shown. Beyond the side wing 29, the wrapper blank has an integral long flap 33 which has substantially the same dimensions as the body portion 27.

The wrapper blank is smeared all over on one side with an adhesive or paste. In applying the wrapper to the package. the body portion 27 is applied to the bottom wall of the package and the side wings 2S, 29 and the two end wings are folded up and secured to the side and end walls of the box, whereupon the margins 32 are folded in and secured to the remaining uncovered wall of the box, and then the long fiap or top flap 33 is folded over and secured to the remaining uncovered wall of the box.

In applying the wrapper to the box, the box is placed in an alined position with the body portion 27 of the blank so that the outline or edges 3i coincide with the edges of the bottom of the box. The wrapper and box are then placed upon the platen of the machine which platen is preferably in the form of a block having the same superficial dimensions on its upper face as the box to be covered, and furthermore, the platen preferably tapers in a downward direction (see Fig. 5). This platen 35 is carried on a spindle 36 which is guided to move vertically in the machine, the lower end of the spindle 36 being preferably provided with threads 37 to receive an adjustable collar 38, and the platen is raised and lowered at the proper times through the medium of links 39 connecting with a lever 40 operated by a cam 11.

lVhen the box and wrapper are placed on the platen and the machine is started, the cam 41 which is carried on the shaft 42 rotates, and the rotation of the shaft 42 operates to depress the plunger 43 through the medium of a cam 4l and a lever 45 which is connected with the plunger 43 at 46. The lever carrying the plunger may be provided with a suitable counterweight 47, and the plunger may be suitably guided in a guide-head 48 forming part of the post 49, extending upward from the upper table 23. The bottom face of the plunger 43 also has the same dimensions as the package so that when the plunger has come down, the box 25 will be held between the plunger and the platen in the manner indicated in Fig. 5. The platen and plunger are then each positively actuated independently by their corresponding cams so as to hold and carry the box down between the wrapper applying instrumentalities which apply the different portions of the wrapper to the side walls of the box. This featuie of positively actuating the platen independentlyv of the plunger may evidently be embodied in machines for covering box shells.

The first operation in this machine consists in carrying the package down between two yielding wipers or brushes 48, the brstles of which engage the side wings 2S and 29 and fold them up against the vertical sides of the box, that is, against the walls that are at right angles to the bottom wall. After the wings 28 and 29 are secured, the end laps or corner laps 31 are folded around the corners of the box and secured to the ends. This is preferably accomplished in the manner indicated in Fig. 6 by means of yielding wipers or brushes which move inwardly adjacent to the ends of the package. The arrangement and mode of operation of these brushes may be as desired. They maybe mounted in the manner shown in Fig. 2, the brushes being supported upon bracket arms 61 adjustably mounted on parallel bars G2 disposed respectively on opposite sides of the throat or opening 63 in the machine through which the box passes. The bars (r2 are preferably mounted on the ends of horizontally guided stems (54. At the proper times these stems are shoved in 'ai-dly. This may be accomplished if desired, by means of two rock levers (35. the upper arms of which .are connected b v a link (3(3 with the rear ends of the stems. the lower arms of the said levers being connected by links (57 with the main rock lever (38 pivotally mounted on a pin 69. This main rock lever (38 is a double bell crank lever having an arm actuated by a slot 7l in a cam T2 carried on said cam shaft 42. After the side wings have been'wiped against the sides of the box by means of the brushes 4S. and before the end laps have been turned about the corners of the box in the manner stated. the box passes on between yielding rollers elf) which roll these vertical walls and insure a good contact between the wings 2S, 2S) and the side walls of the box. This downward movement continues and similar devices operate to fold the end wings 3() of the wrapper against the-end walls of the box. These latter mentioned devices preferably comprise two brushes 51, the bristles of which engage the end wings il() so as to wipe them up against the ends of the box, after which the package continues its downward movement between yielding rollers which roll the attached wings 30 against the end walls of the box. The rollers 49 and the brushes 48 are suitably supported in arms 53. The rollers 49`and 52 are prefeml'ilyr of a soft material such as rubber. 1f desired, the rollers may be resiliently yielding by means of any suitable construction such as that indicated at 54 in Fig. 1, in which the gudgeons 55 at the ends of the rollers are supported in brackets 5G, which brackets have stems 57 passing through supporting brackets 58, the backward movement of the stems being resisted yieldingly by means of coil springs 59 disposed around the stems. After the two side wings 28, 29 and the end wings 30 have been folded up and secured to the vertical walls of the package, it is then necessary to fold over the margin flaps 32 to secure them to the remaining uncovered wall of the box. In order to accomplish this, the cam 44 is preferably constructed so that at the desired moment the plunger 43 will withdraw slightly in the manner indicated in Fig. 11. withdrawing the plunger in this way, of course, leaves the box on the platen unsupported. e

Any suitable' means may be provided for holding the box on the platen when the plunger has withdrawn in the manner suggested. However, for this purpose there is preferably provided a pair of oppositely disposed cleats which engage the opposite ends and corners of the box. These cleats are automatically actuated to move inwardly at the proper time by a mechanism presently to be described and associated with the members or brushes which cause the margins to fold over and secure themselves to the uncovered wall of the box. To fold over the margins 32, there is provided a pair of oppositely disposed folding members or brushes 7l. These brushes are preferably supported on suitable cuide stems such as the guide stems in l* ig. S), which are emlployed with a third brush or folding member 76. This brush T6 is similar in its functions to the brushes 74, but is made extensible and collapsible so that all three of the brushes may be advanced simi'iltaneously. As the brushes 7l move inwardly toward each other, the brush 7b moves inwardly betweenthem, but on account of its being collapsible, it does not obstruct their free inward niovement. Any suitable construction such as this may be adopted for the brush 7G to enable it to allow for the presence of the other brushes or folding members. This arrangement enables these instrumentalities or brushes to operate simultaneously upon the same wall of the box without interfering with each other.

In the present instance the brush 76 is shown as consisting of a body member with extensible heads 7T at each end, said heads being pressed outwardly by a spring 78 and guided by means of guide stems 79, sliding in suitable sockets in the ends of the brush.

llO

These three brushes are all moved inwardly bymeans of links 80 which are attached preferably at the middle points of the backs. of the brushes. When the end brushes 74 move inwardly the mechanism which operates them automatically moves in the clamping cleats 73. For this purpose, the cleats are carried on suitable guide stems 81 (see Fig. 1) guided in the frame, and the links 80 are attached to small rockers 82. These rockers have cams 83 which engage the backs of the cleats and force them inwardly. At the same time, as the rockers 82 swing inwardly, they operate to shove in on the links 80 so as to cause the brushes 7-1 to move transversely to the uncovered side of the box. A similar mechanism is provided for giving the intermediate brush 76 the same kind of a movement. the rockers 82 corresponding to the three brushes, being actuated simultaneously by means of a rising and falling crosshead or sleeve 84 having three arms 85 which carry u-pwardly projecting stems S6 which are connected by links 87 with the aforesaid rockers 82. However, the intermediate brush 76 moves faster and further than the other two brushes. This is accomplished by Inaking the arm 82 of the rocker corresponding to thebrush longer than the corresponding arms of the other rockers (see Fig. 2). The box is now adherently covered on all sides except one remaining uncovered wall which in this instance is the upper wall of the box. The machine now operates to fold down the unattached area of the wrapper. and secure it to this uncovered wall. This is accomplished by any desired means which will operate to press the remainder or unattached area or portions of the wrapper against the remaining uncovered wall throughout the entire area of this wall. In the present instance, this operation consists in folding down and attaching the long flap 33, and in the present instance this is accomplished by giving the partly covered box a lateral-movement away .from the plunger and platen. During this lateral movement the long flap is folded over and secured adherently to the box. In order to accomplish this, there is provided an ejecting device 89 (see Figs. 2 and 13), which device preferably comprises a pusher 90 having a head 91 carried on two parallel guide bars 92 which are supported and guided in suitable guide brackets such as the guide bracket 93, so as to enable the pusher to move in a horizontal path and transversely to the axis of the plunger 13 and the platen 35. In order to actuate this pusher at the proper time, preferably the bars 92 are provided with a rigid and adjustable crosshead 94 which is attached to a link 95 connectedfto a lever 96. This lever is mounted on a pivot 97 and is operated from time to time by a cam 98 on the cam wheel 72. The lever 96 has a roller 99 which lies near the cam wheel 72. When the cam 9S comes around it strikes the roller and operates the lever to push the crosshead and pusher inwardly, this movement being resisted by a coil spring 100 arranged around a stem 101 which is pivotally attached at 102 to the lever, aud which slides freely through a guide 103. At the proper time this pusher 90 advances in the manner indicated in Fig. 13 so as to shove the package 25 oli' the platen In order to fold down the long flap 33, it is preferable to provide near the path of lateral movement of the package, a fixed wiper or brush 101, the bristles of which are arranged so that they will slightly press the upper wall of the package when the box passes under the brush. This mode of operation is clearly illustrated in Figs. 11 and 12.

It is understood that brushing a flap of the wrapper by yielding bristles in this way in applying it to the box is desirable because it removes the air bubbles or blisters which may tend to form between the wrapper and the wall of the package. In order to prevent the formation of any such blisters on the bottom wall of the package, it is also desirable to brush the bottom of the package while the same is having this lateral movement. For this purpose, an auxiliary brush 105 is provided which is preferably adjustable in a vertical direction. For this purpose the brush is preferably formed on a bracket 106, the ends of which are formed into adjustable clamps 107 received on downward extending guide bars 108 formed in the frame. The bristles 109 of this brush 105 project upwardly through an opening 110 in a. plate 111. This plate 111 forms an extension of the bottom plate 112 of a chute 113 which receives the package after it passes the brushes 104 and 105 (see Figs. 12 and 2). This chute curves laterally and downwardly, preferably as indicated in Figs. 2 and 13, so as to deliver the package at a convenient point.

In Fig. l-l is illustrated the completely formed sealed wrapped package 114, and in this )ackage the long fiap 33 forms the upper face. The long iiap is usually printed upon so that in the completely covered box it forms a label. Means is provided for insuring that the pressure of the plunger and platen on the package will not be great enough to injure the box. This pressure is preferably a yielding or spring pressure.

n order to accomplish this, the spindle 3G is preferably not rigidly attached to the platen, but the platen has a shank 115 (see Fig. 2) having a. pin and slot connection 116 in the upper end of the spindle which is tubular at its upper end, and in the bore of the spindle at this point a helical spring 117 is provided which thrusts against the end of the shank 115. The machine is adjusted so that the spring 117 will be slightly compressed when the plunger and platen are iolding the package. By reason ot this spring evidently the plunger and platen will adapt themselves to hold and carry packages of slightly different depth. rThis overcomes any necessity for a very accurate construction ot the cams which control the plunger and platen. In other words, the spring allows tor the slight variations in the depth of the boxes. The cam shaft 42 may be driven by a belt pulley 118 and clutch 119 through the medium of a worm 120 and worm-wheel 121. In order to assist the machine operator in feeding the boxes and wrappers to the machine adjustable corner gages 122 are provided (see Fig. 2l which insure alinement of the box and wrapper with the platen.

The blank as shown in Fig. 3 is preferably formed so that the marginal portions 32 are ot' the same length as the wings or flaps of which they form a part. and the ends of these marginal extensions are preferably clipped on an inclined line. On this account. when these portions are folded in on to the remaining uncovered wall of the box, they simply lie tlat upon the wall without producing any doubled edge or gusset fold. At this point and at all other points of the wrapper there are no overlapping portions of the wrapper that are not either adherently attached to the wall. of the box or to the other portions of the wrapper. Thus. we absolutely eliminate the presence of crevices in which insects might lind lodgment. lVhen the box is completely covered with the wrapper. the portions of the wrapper which correspond to the different walls have their edges coinciding with the edges of the package so that the printed matter indicated at 355 on the wrapper presents itself properly alined and the same effect is produced as though dierent labels had been applied to the dilerent sidesl of the box which carry the printed matter.
